Tetkoba, you and your friends have designed one of the most elegant and easy to make alcohol stoves I've seen! Thank you for your efforts and generosity!
I just made one - my first can-based alcohol stove! It took about 2 hours from start to finish, including sanding off the paint. AND IT WORKS!! Many thanks Tetkoba-san. In the UK, you can get Diet Coke cans the same size as Red Bull. Next time. I'll sand the can before emptying it and drill the jet holes before fitting the top ring.
Thanks for the diet coke recommendation - hopefully I can find it in the US because Red Bull is expensive as heck and I know I"m going to mess it up a few times!
This is awewome, and for more than one reason. Not only the stove is an amazing piece of work, but the whole video is entertaining and enriching. The explanations are quick, efficient and clear, the music is perfectly chosen, the graphics are helpful to understand how the stove works, and there are nice tests made at the end of the video to show what to expect from the design. I cannot think of a better way this could have been made, thanks a lot!
Took this stove on a 3-day hike. I've been using penny stoves/can stoves for years, using lots of different designs, and this is simplest most efficient alcohol stoves I've ever used. Now if you can only design a simmer ring for extra long burns, it'll replace all my other can stoves :)
This is a great design. I've been messing around with a slightly different jet pattern and size. A stove I just made yesterday is boiling 500ml of water in only 4:15. I'm using V8 tomato juice cans in 5.5oz size. The final height of the stove is 38mm. The jet pattern I'm using is 10 jets, with alternating size of 0.85 and 0.65mm. I'm using 20ml of denatured alcohol which burns for 5:00-5:30 total. The kettle I'm using is a MSR Titan 750ml titanium
I built a variety of alcohol stoves many years ago, with a fairly deep dive into engineering for simplicity and efficiency. I'm preparing to embark on a new time wasting recreation to create a fast boil stove for tea and the occasional freeze dried pouch of expensive salty disappointment, and a long burn simmer stove for pasta and rice dishes. I have a pile of 5.5 ounce V8 cans queued for the experiments. I think I'll make a Spiguyver (capillary) stove for the fast boil and my own non-penny version of the penny stove for the slow simmer stove, although I can't help trying a super simple version that's basically a squat can with eight jet holes in the side near the top.
Tetkoba san, your creations are fascinating to me. Using some rough numbers, it seems that this CHS universal version puts out over 1 KW (1120 W) of thermal power, and bringing to a boil 400 cc H2O required about 140 KJ of energy. So your awesome stove was around 35% thermally efficient. Better than any that I’ve seen anywhere, by a long shot. My sincere respect and admiration!
This is very impressive, I have seen other capillary stoves but they have always had somewhat complicated builds. This is simple and effective, very clever!
Tetkoba-san, You are the BEST stove builder HANDS DOWN! Your designs are innovative, technically superior and (as luca bravo wrote) exquisite. Your videos are well done and I enjoy watching them. I built a CHS today following your video and tips and it turned out perfect. I did a side-by-side comparison against the specs in your video and the weight, burn and boil times were all identical. I love this stove! Keep up the good work!
Thank you for your trying! Yes, I think CHS has a ultimate operating principles. It is a still developing technique. I hope many people try this and evolving.
Yay, I made one of these last night and it works well. First burn test this morning... maybe I'll do a boil test tonight. I had some problem with the small holes required... Normal drill kits don't go down this small here, and a pin isn't strong enough to go through the can at this point. Finally found some smaller drills yesterday. Success. Thanks for the elegant design, tetkoba.
As always, your stove is a triumph of beauty and function. I would love to see a more detailed video of the forming of the creases as I'm not sure I understand teh process for making them. Well done!
Thank you for sharing. The video is a very good demo of some important design improvements. I like how time till jets go on has been reduced to just 5 seconds and that they run a full 10 minutes on very little fuel. These features, combined with the ease of making them (with no JB weld! Very good), is inspiring.
Thank you for your reply i preferred to use a little JB weld between the joint to ensure an airtight fit. It works very well, I also tried a 57mm dia can and added one more jet and also 5mm to the height. the larger version is very powerful and good for boiling 4 cups of water with 40cc fuel, I think this is your ultimate design. keep it up
Thanks so much for showing this. I always have been inspired by your craftsmanship as well as your constant development of alcohol stoves. If you have an ebay, I may just purchase one of your units! LOL!
I builded this today and gave it a try. Burns Well an Not so uncontrolled like others. But for the cost of the three needed Cans. I can nearly buy one.
Great video. Think I will try to make this for fun. From the videos I seen so far on alcohol stove, the best distance between water pot and jet is approximately 1 inch or 25mm. With that kind of intense heat you have on this stove, I think it can boil much faster. Good job.
Very slick! I like your professional presentations, no speech, just music, unlike so many of the usual crop of ditherers who drift off topic, ummm, ahhh, backtrack, or get interrupted by other irrelevant events in their workshop, or have infuriating camera-shake. You only have the key items, clearly shown, in sequence, with text where required. And it works. This is why almost all Japanese stuff works, and is reliable, just like Toyota, as it's all attention to detail. Good job, guys. :-)
+John Brown And the videographer is gracious to present an explanation in English before his own language. His manners set a high standard for all videos to follow,.
+John Brown... Gosh John, could you please practice at giving a compliment without insulting others or using sweeping generalizations ? Perhaps using just the first seven words above along with the last three? Lastly consider that there is NO relationship between a presentation and the quality of the product presented. either one, or both, can be bad or good. Just some things to think about...
Great video, thanks for posting. I have just improved performance by using some fine copper wire taken from a dimmer switch. The copper wire slightly proud of top is heated by the flame which then heats the methylated spirits. Big flames!! 😈
Hi, thanks for spending the time and effort experimenting to create this simple and beautiful stove. Have you considered placing the capillaries at an angle and experimenting with variables of angle and smoothness of the surface by using different grit when sanding the interior components? Thanks for sharing your work.
Have built several CHS-U stoves and though not so pretty as tetkoba's perfection the stoves are amazing. If not perfect each build burns at claimed burn time for amount of fuel with flawless operation. Worth the extra effort versus other builds I have tried.
I will, in fact, I would like to tweak it so that it burns very slow… I don't know how long you can make it last. While this is awesome for cooking, an indoors alcohol based oven (your stove covered with 2 masonry pots, like I saw on a video) might also be possible to get. I think it can be very useful to warm the room cleanly and cheap. What do you think ?
Planning to make one of these in a day or to and will change one small thing just to see what effect it will have. I'm going to angle the crease so the alcohol is being sucked up the same direction of the jets. I do not think it will make much difference but I'll post back here if anything noticeable happens.
I just finished my first alcohol stove! It was a simple soda can penny stove design, but I aimed the jets in like you do (but straight, not cyclone). The 16 jets were made with a thumb tack (maybe 1mm). My first burn was with 80mL of fuel. At 1:40 it turned from a dancing blob into a bright blue solid primary cone with a beautiful blue dancing spirit above it (no orange). The spirit began to die @ ~47:00, and the flame went out at 52:21 Thank you for your examples and inspiration, tetkoba san.
I finally made one of these using 200ml solo cans. Its not very precise but works well despite not being as beautiful as yours. Hot tip, 🔥 don't over hear the rim when annealing it to fold it over.
Loved this video. It's seams to be a very effective alcohol stove that burns 30 cl alcohol in 11 minutes and boils water in 5 minutes. More efficient than the Trangia alcohol stove. Higher efficiency also means higher alcohol consumption.
Higher efficiency means lower alcohol consumption. Faster boil times generally mean higher alcohol consumption because they're creating more heat quicker, which often also means more wasted heat alongside that. Faster boil ≠ "more efficient." Less fuel used for same temperature raise = "more efficient," despite the amount of time taken. 👍
I made a side-burner version of this stove, only issue is that it is longer burn time with stove sitting right on can. Ultimately I feel you probably still need a stand even with a higher lip and sideburners. I will test boil times with stand and maybe see if my hypothesis is correct
very lovely work of art master tetkoba,,,but you say only 1 oz fuel was used? seem more like several ounces in that beaker,,but i bow to your work and craftsmanship
Yes I watched it. I used like I said a small x-acto knife and it took several passes and ended up sawing the can with it after I think 20 scratches. I think I have found the style/type of knife you use.
As I said in a another comment on your channel: Great craftsmanship! I study Japanese martial arts, and can really appreciate Japanese attention to detail. I also build boats and have studied Japanese boat-building techniques. You guys have patience and are very meticulous. Thank you very much (Domo arigatto!).
Hello TetKoba, What elevation do you test your stoves at? I built a modified version of the universal hoop stove eliminating the lower hoop and inner jets I stopped the capillary tubes half way up the inner capillary section and jetted it to the outside at this point. The results were stunning 3:40 min. boil time using tap water and denatured alcohol with a burner to pot distance of 1 1/4"-- @ 4600' elev. and room temps. using a typical titanium 1 quart. backpackers pot and lid. I have since built two more of these stoves experimenting with jet height/size and have had favorable results! My background is Field testing for outdoor equipment companies and have, over 40 years+ got t use just about every type of stove and fuel source available-- this great alcohol stove simplicity and performance that we are seeing especially with your stoves, got my attention! Thankyou for all the great video's and guidance! Lightning Layne-- Professional field tester at large!
Stupendous! This looks like the perfect design! I commend you for your ingenious efforts with alcohol technology. The fuel efficiency is superb with a strong pressurized flame. I love it! BoilOn!
***** Hi Tetkoba, I just have a few questions about the CHS-SB., 1.How many creases did you put in the CHS-SB? 2.Should I put 16 or 18 creases? 3.How does the number of creases affect performance? 4.IMPORTANT:After completing my CHS-SB and after folding the outer to inner I drilled my jet holes 10mm from the top of my stove and it was less far from the top of the stove as what it looked like in your video of the CHS-SB. In other words, I did what you told me but, however, there was a bigger space between the jet holes and the top on your stove then my stove. What should I do About that? Thanks Tetkoba! Keep up the great work!
Aqua Dog's Adventures in Toontown Rewritten ! 1. Forgot.2. as you want. 3. short burn time and more power when many creases. 4. Position of the holes farther than 10mm. Meaning of "10mm" is increment value of height of top piece.
thanks, here I am camping with your stove on top of a small upside down stainless bowl with the bowl I cook in supported by three tent pegs in the ground surrounded by a disposable oven tray. small red bull metho stove in action I find the base you cut off the capillary tube makes a great extinguisher or dampener to slow cook too.I shall try the chs side burner next as it would seem to eliminate the need to get the distance between the pot and the cooker right
Thank you for your time! I have 2 last questions... haha! 1. How far are the jets from the top of the CHS-SB? 2.I am building a pot stand for CHS-U. How far should the top of the CHS-U for best performance? Thanks again!
Aqua Dog's Adventures in Toontown Rewritten ! 1. 10mm.2. Depend on your jet angle. Don't ask me angle because no data(my hand feeling). Try and error!!
I have tried to make this stove 3 times now and always end up with a big orange flame in the middle. What am i doing wrong? Please help as i really want to use this stove for camping but just cant get it to work. great videos and fantastic stove thank you for sharing.
What are the ingredients of the alcohol you use? If it contains a lot of ethanol, it becomes an orange flame. Alternatively, the jet holes may be large and the amount of vaporized gas ejected may be large, causing oxygen deficiency. Hope this helps.
@@tetkoba I am using bio ethanol as a fuel. The flame is also large in the middle, you can see the jets but not as clear as in your videos. what fuel do you suggest? i will try something different before trying to make another stove as i am spending a lot of time without reward and losing motivation. I really want your excellent stove to work for me because they look so efficient and i enjoy making my own equipment especially when the results look better that shop bought alternatives. Thank you for replying to my email. Good health Mark
This is great and a very useful tip, Tetkoba-san (Did I use it right haha) I was looking into buying a spree(Ethanol) operated stove or Trangia, but they are so expensive. I think I will just have to start drinking Redbull, not gonna succeed on first try. Greetings from Finland :)!
This is my favorite burner so far and I would like to try to make this but a little bit more instruction would be helpful. Is there someplace else to look for instructions on assembling this?
I really enjoy your tutorials on the alcohol stoves. I am living in Japan and would like to know what fuel you are using. I bought 無水エタノール。But it is really expensive. 1300 yen for 500ml! If you could post a picture of the label it would be easy to search for in the shops. Thank you.
Thanks comment. Watch ua-cam.com/video/53aonESDlGE/v-deo.html . I purchased from Joyful-Honda(DIY/HomeCenter) at 208JPY/500ml. I think it is the cheapest. If you living any other Kanto, visit DIY/HomeCenter near you, and go to coffee goods corner. Or visit any drug store and ask shop stuff as "Nenryou Arukohru". Price is 350-650JPY/500ml. Hope this helps.
isopropyl alcohol? 70% or 90%? ethyl alcohol / grain spirits, 70+% (aka Everclear in USA)? or needs something less common, like >96% denatured alcohol, or worse, methanol? how hot does it run on ordinary fuels? can it melt electronics solder? solder copper pipe and melt glass like a butane torch? melt zinc or bronze for metal working??
Exelente me encanta el funcionamiento, pero me gustaria saber como realizar la parte interna; los cortes como deben de hacerce para fabricarme una. Felicitaciones!!!

I just made one using this tutorial. It looks almost exactly the same, works great. It took me some 4 hours but it is worth it. Thank you dude!
Best of the best! Great Learning and really enjoyed watch through your series of development.
Thanks for sharing, really capable little stove!!!
Yes. Power will be down when smaller center hole. But it is more effective to close the jet hole.
Thanks so much for showing this. I always have been inspired by your craftsmanship as well as your constant development of alcohol stoves. If you have an ebay, I may just purchase one of your units! LOL!
tetkoba, all of your work is highly inspirational to me. I plan on building this model soon. Thank you!
Another excellent video and your new design certainly looks like a winner. Great job!
Thank you for sharing your knowledge with all of us !!! God bless you !!!

You are the master, Tetkoba! Thank you for your detailed instructions. This stove is incredible! It worked far better than another design I tried.
best stove with amazing music and state of art explain, exquisite craftsmanship
Thank you for bringing the concentrated technological strength of Japan to the world of alcohol stoves - we are all better off for it!
Very slick! I like your professional presentations, no speech, just music, unlike so many of the usual crop of ditherers who drift off topic, ummm, ahhh, backtrack, or get interrupted by other irrelevant events in their workshop, or have infuriating camera-shake.

This is why almost all Japanese stuff works, and is reliable, just like Toyota, as it's all attention to detail.

Fantastic design and execution. Thanks!
JBウェルドを使わないトルネードのアルコールストーブを作れないかなと思い、色々動画を見ていたので、こちらの動画はまさにドンピシャでした。
立ち上がりの早さも火力も見た目のキレイさもイメージしていた以上で素晴らしいです。
製作はかなりシビアな様ですが近々挑戦してみたいと思います。
しかし不思議なのは、完成度の高いアルコールストーブの動画はどれも日本語のコメントがとても少ない事です、海外からのコメントが圧倒的ですね。
日本人はこういう工作に興味ある人は少ないのでしょうかね、こんなに楽しいのにもったいない。
隙間を完全になくすにはかなりの精度が求められるんで、結構難しいと思いますよ。まあ多少漏れていても充分な気化量があるんで実用には問題ないですが。ひと缶で作るeCHSのハウツー動画に、JBweldを使わない方法も紹介してるんで、そちらも参考にしてくださいな。
日本の方々は欧米の皆さんに比べて長期トレッキングの経験が少ないでしょうから、シビアな環境だったり総重量だったりの経験が足りないんでしょうね。だから良し悪しの判断もつかない。よくある逆輸入じゃないと良いと認識されない日本人的性質の表れと思ってます。
Thank you for an excellent video of a very good design.
Longest video I've seen so far from you. Great burner. Will try to build one as well...
Have built several CHS-U stoves and though not so pretty as tetkoba's perfection the stoves are amazing. If not perfect each build burns at claimed burn time for amount of fuel with flawless operation. Worth the extra effort versus other builds I have tried.

Loved this video. It's seams to be a very effective alcohol stove that burns 30 cl alcohol in 11 minutes and boils water in 5 minutes. More efficient than the Trangia alcohol stove. Higher efficiency also means higher alcohol consumption.
Higher efficiency means lower alcohol consumption. Faster boil times generally mean higher alcohol consumption because they're creating more heat quicker, which often also means more wasted heat alongside that.
Faster boil ≠ "more efficient." Less fuel used for same temperature raise = "more efficient," despite the amount of time taken. 👍
I made a side-burner version of this stove, only issue is that it is longer burn time with stove sitting right on can. Ultimately I feel you probably still need a stand even with a higher lip and sideburners.
I will test boil times with stand and maybe see if my hypothesis is correct

4. Position of the holes farther than 10mm. Meaning of "10mm" is increment value of height of top piece.
thanks, here I am camping with your stove on top of a small upside down stainless bowl with the bowl I cook in supported by three tent pegs in the ground surrounded by a disposable oven tray. small red bull metho stove in action
I find the base you cut off the capillary tube makes a great extinguisher or dampener to slow cook too.I shall try the chs side burner next as it would seem to eliminate the need to get the distance between the pot and the cooker right
Very interesting and inspiring video. Thank you!
Great job. Well done.
Great job on the stove. I don't know how you're going to top this one.
Great work man, I loved this Stove, easy making, I'll try it, thanks...
Insightful and clean - thank you
Very cool. You have built some amazing stoves. I would like to build one of these. How did you put all those creases in the side of the can? Thanks!
amazing work sir!!
こんにちは！
とてもカッコイイ、観ていて造りたくなる動画でした。
今度、私も挑戦してみます。
Redbullをたくさん買わなくては！
black label golden star コメントありがとうございます。RedBull缶なら2缶でも作成可能。失敗しないためにトップとインナーをJBウェルドでシールしておくと良いですよ。
Great work as usual, I wait for the next one with impatience. Thx.
Masterpiece collaboration!
Ich liebe Japan! Herzlichen Dank für dieses Video. Viele Grüße aus Kassel.
Der Herkules lässt grüßen :-)
auf den redbull dosen steht in deutsch : belebt geist und körper

How do you crimp the sides of the inner container? Thank you 🙏🏽🇬🇧🇯🇵
congratulations, you are a true genius
Thank you for your time!
I have 2 last questions... haha!
1. How far are the jets from the top of the CHS-SB?
2.I am building a pot stand for CHS-U. How far should the top of the CHS-U for best performance?
Thanks again!
Aqua Dog's Adventures in Toontown Rewritten ! 1. 10mm.2. Depend on your jet angle. Don't ask me angle because no data(my hand feeling). Try and error!!
I have tried to make this stove 3 times now and always end up with a big orange flame in the middle. What am i doing wrong? Please help as i really want to use this stove for camping but just cant get it to work. great videos and fantastic stove thank you for sharing.
What are the ingredients of the alcohol you use? If it contains a lot of ethanol, it becomes an orange flame. Alternatively, the jet holes may be large and the amount of vaporized gas ejected may be large, causing oxygen deficiency. Hope this helps.
@@tetkoba I am using bio ethanol as a fuel. The flame is also large in the middle, you can see the jets but not as clear as in your videos. what fuel do you suggest? i will try something different before trying to make another stove as i am spending a lot of time without reward and losing motivation. I really want your excellent stove to work for me because they look so efficient and i enjoy making my own equipment especially when the results look better that shop bought alternatives.
Thank you for replying to my email.
Good health
Mark
@@tractionmanuk I think it's because of bio ethanol. My fuel is 5% ethanol 95% methanol. I think 30% ethanol 70% methanol is also fine.
This is great and a very useful tip, Tetkoba-san (Did I use it right haha) I was looking into buying a spree(Ethanol) operated stove or Trangia, but they are so expensive. I think I will just have to start drinking Redbull, not gonna succeed on first try.
Greetings from Finland :)!
This is my favorite burner so far and I would like to try to make this but a little bit more instruction would be helpful. Is there someplace else to look for instructions on assembling this?
I really enjoy your tutorials on the alcohol stoves. I am living in Japan and would like to know what fuel you are using. I bought 無水エタノール。But it is really expensive. 1300 yen for 500ml! If you could post a picture of the label it would be easy to search for in the shops. Thank you.
Thanks comment. Watch ua-cam.com/video/53aonESDlGE/v-deo.html . I purchased from Joyful-Honda(DIY/HomeCenter) at 208JPY/500ml. I think it is the cheapest. If you living any other Kanto, visit DIY/HomeCenter near you, and go to coffee goods corner. Or visit any drug store and ask shop stuff as "Nenryou Arukohru". Price is 350-650JPY/500ml. Hope this helps.
isopropyl alcohol? 70% or 90%? ethyl alcohol / grain spirits, 70+% (aka Everclear in USA)?
or needs something less common, like >96% denatured alcohol, or worse, methanol?
how hot does it run on ordinary fuels? can it melt electronics solder? solder copper pipe and melt glass like a butane torch? melt zinc or bronze for metal working??
Exelente me encanta el funcionamiento, pero me gustaria saber como realizar la parte interna; los cortes como deben de hacerce para fabricarme una. Felicitaciones!!!
Another great "Tetkoba". Ty, chris
